INTEGRATION OF RESID HYDROCRACKING AND HYDROCLEANING Russian patent published in 2017 - IPC C10G65/02 C10G65/10 C10G67/02 C10G47/30 C10G49/16 

FIELD: oil and gas industry.

SUBSTANCE: one of the process variants includes the following steps: contacting the hydrocarbon residue and hydrogen fraction with the first hydroconversion catalyst in the first fluidized bed hydroconversion reactor system; extracting the first outlet stream from the first fluidized bed hydroconversion reactor system; contacting of the first outlet stream and hydrogen with the second hydroconversion catalyst in the second hydroconversion reactor system; extraction of the second outlet stream from the second hydroconversion reactor system; contacting of the second outlet stream and hydrogen with the third hydroconversion catalyst in the second fluidized bed hydroconversion system; extracting the third outlet stream from the second fluidized bed hydroconversion reactor system; fractionating of the third outlet stream from the second fluidized bed hydroconversion reactor system to recover one or more hydrocarbon fractions, including the vacuum fraction of the hydrocarbon residue.

EFFECT: invention makes it possible to achieve high hydrocarbon processing using a simplified technology.
